Keeping Traditions Alive Since 1953

Slim single-stack Glocks like the 42, 43, 43X, and 48 are some of the most carried pistols out there, and the factory sights leave plenty of room for an upgrade. The AmeriGlo Protector set (GL-352) takes the popular front-sight-focused approach and applies it to these compact carry guns, giving you a much clearer aiming reference when the light drops off.
The front sight uses a green tritium lamp wrapped in a high-contrast LumiGreen ProGlo outline. That means the vial glows on its own in the dark for true 24/7 visibility, while the bright green ring around it grabs your eye fast in daylight and dusk. The rear is a black, serrated U-notch design that stays deliberately plain. There are no distracting dots back there, so your focus naturally lands on the front post where accuracy actually comes from. The serrations also knock down glare and give you a ledge you can hook on a belt or holster for one-hand slide manipulation if you ever need it.
This Protector layout is patterned after AmeriGlo's U.S. federal government contract sights, so it is a proven setup rather than a gimmick. The matte black finish keeps things low glare, and the low-profile blades tuck away cleanly for concealed carry and smooth draws.
One set covers the Glock 42, 43, 43X, and 48, including MOS series slides, so you are not hunting for a model-specific part number. The front blade runs 0.140 inches wide, matching the familiar Glock sight picture most folks are already used to. Installation is straightforward with basic sight tools, though a lot of owners have their local shop press them in and confirm zero. If you carry one of these slim nines and want a sight setup you can trust in the dark, the Protector set is a smart, no-nonsense move.
Yes. The GL-352 set is made for the Glock 42, 43, 43X, and 48, and that includes MOS series slides. One part number covers all four of these slim Glock models.
It does. The front sight has a self-powered green tritium lamp that stays lit in total darkness without needing to charge up from a light source. During the day, the LumiGreen ProGlo outline around the vial gives you a bright, high-visibility aiming point.
That is by design. The plain black serrated U-notch keeps your eye from getting pulled to the rear and pushes your focus onto the front sight, which is where consistent accuracy comes from. The serrations also reduce glare and give you an edge for one-hand slide racking.
The front installs with a 3/16 nut driver and the rear presses into the dovetail, so it is a manageable job with the right tools. That said, a lot of owners have a gunsmith or their local shop press the rear in and verify zero to make sure everything is dialed correctly.
